Rear riser card replacement

Use this information to remove and install a rear riser card.

Server rear configuration and riser assemblies​

See this section to identify the correlations between the rear configuration and riser assemblies.

Note

  1. The illustrations of riser brackets and cards may look slightly different from the physical ones.

  2. BF: “butterfly”, a riser card with slots on both sides.

  3. When a Gen 5 BF Riser 1 card is installed, only slot 2 can support Gen 5 PCIe adapters.

  • Depending on the server configuration or specific orders, the riser card can be a Gen 4 or Gen 5 card.

  • This section only breaks down how to match the cards with the brackets as the appearance and the installation methods are the same for the Gen 4 and Gen 5 BF cards.

This card can be:

  • A Gen 4 riser 1 card

  • A Gen 5 BF riser 1 card with one slot removed
